Tourette's How do schools help pupils.

Basically there is a new child joining the school with Tourette's and I was hoping for advice with how to help. I do not know enough about this condition . I thought it best to ask the people who really know what would help the child the most. At the moment he is at the ticks stage and just a little bit of calling out. So is there anything that can be done to make the child less stressed and happy. Not to try and stop the Tourette's behaviour but just to make his life easier.If anyone has any advice at all it will be gratefully received.
